Hosted by Trinity Innovation Knowledge Exchange, the workshop highlighted progress from a collaborative research and development project transforming bauxite refining residue, often known as red mud, into low-carbon cement and concrete materials. 

The project addresses one of the construction sector's most pressing challenges: reducing the carbon footprint associated with cement production while finding valuable uses for industrial by-products. By incorporating bauxite refining residue into cement and concrete formulations, the research team is exploring new pathways towards more circular and resource-efficient construction materials. 

Attendees from academia, industry and the construction sector heard how the project has progressed from laboratory-scale research to industrial-scale production and testing. Presentations outlined the development of full-scale concrete blocks, ready-mix concrete applications and industrial trials, demonstrating the potential for the technology to move beyond research settings and towards commercial deployment. 

The workshop also provided an opportunity to share findings on material performance, durability testing and carbon footprint assessments. Participants viewed material samples and demonstration products developed through the project and discussed the technical, regulatory and commercial considerations involved in bringing new low-carbon construction materials to market. 

Funded through Enterprise Ireland's Innovation Partnership programme, the initiative brings together researchers from Trinity College Dublin and industry collaborators to accelerate the development of lower-carbon technologies for the built environment. 

Professor Sara Pavia and the project team also outlined the next stages of development as the research moves towards wider industry adoption and commercialisation opportunities. 

The School of Engineering would like to thank everyone who joined the workshop and contributed to the discussions throughout the day. The engagement, questions and insights shared by attendees helped create a valuable forum for exchanging knowledge between researchers, industry practitioners and innovation leaders working towards a more sustainable construction sector.
